The acquisition equipment can receive the acquisition message through the active antenna, and responds to an acquisition instruction in the acquisition message to acquire the electric power data corresponding to each ammeter in the acquisition area. The electric power data recorded in the electric meter can be used for representing the total electric power used by the electric power user corresponding to the electric meter.
In one possible implementation, the master station server may also send a configuration file to each of the collection devices to configure the collection mode of the collection device prior to collection of the power data by the collection device. The acquisition modes of the acquisition device may include an interval acquisition mode and a trigger acquisition mode. When the collection device is configured in the interval collection mode, the collection device may collect power data of each electric meter at intervals according to the time interval in the configuration file. When the collection device is configured to trigger the collection mode, the collection device can collect power data corresponding to each electric meter in response to the collection command after receiving the collection command sent by the master station server.
S102, the acquisition equipment sends Beidou short messages containing the electric power data to a communication satellite so as to transmit the Beidou short messages to a master station server through the communication satellite; the Beidou short message is generated based on a satellite communication protocol between the communication satellite and the acquisition equipment.
In this embodiment, after the collecting device collects the electric power data, the collecting device may generate the beidou short message corresponding to the electric power data according to the satellite communication protocol between the communication satellite and the collecting device. The acquisition equipment can send the big Dipper short message containing the electric power data to the communication satellite to say big Dipper short message transmission to the master station server through the communication satellite.

The length threshold in the acquisition device may be the maximum data length that can be transmitted by the data frame of the beidou short message.
In one possible implementation, if the acquisition device determines that the data length of the current power data is less than or equal to the length threshold, the acquisition device may encapsulate the current power data into the beidou short message data frame according to the satellite communication protocol.
